(More customer reviews)"Massive Bridges" tells the story of two large bridges given new lives after being moved to new locations. The first was in Iowa - a 130-year-old road bridge no longer able to carry the weight of today's vehicles. It was moved 56 miles to provide a new foot bridge in an Iowa park.
Army Chinook helicopters from the Iowa National Guard were used to accomplish this, with crews gaining the experience as part of another training mission. Ground crews had to hook up bridge sections to the hovering Chinooks while underneath in its "hurricane-wind" downdraft (about 140 mph). The Chinook's twin 4,900 h.p. motors strained to maximum power to move the largest single section of the three.
In Kansas City, an 1890 abandoned and rusty railroad bridge was to be moved to a new location, also to serve pedestrians. The 237' 1840-design bridge weighed 290,000 lbs. and had to be split in half, then transported on 48-wheel trailers. The railroad traffic was halted for six hours to allow the bridge to be placed onto the trailers and moved away. Moving through parts of the old downtown then required 100 electricians to take down and replace light fixtures and overhead wiring.

Bridges move people and cargo daily, but what happens when the bridge itself needs to be moved? In this episode, we see how two very different bridges are moved--using two very different methods. In Missouri, local bridge preservationists attempt to transport a 137-ton railroad bridge right through the heart of downtown Kansas City. And in Iowa, the National Guard rallies to save a 129-year-old bridge using one of the most modern mega-moving tools available: a Chinook Helicopter. Will our Mega Movers succeed in preserving these beloved bridges for future pedestrians to use?
